在app中的App Purchase Receipt验证中

Question

我想在我的应用中验证交易收据,

这是我的代码,

- (void)recordTransaction:(SKPaymentTransaction *)transaction {

    NSData *receiptData = [NSData dataWithData:transaction.transactionReceipt];

    NSString *encodedString = [Base64 encode:receiptData];

     NSURL *url = [NSURL URLWithString:@"https://sandbox.itunes.apple.com/verifyReceipt"];

    ASIFormDataRequest *request = [[ASIFormDataRequest alloc] initWithURL:url];

    [request setPostValue:encodedString forKey:@"receipt-data"];

    [request setRequestMethod:@"POST"];

    [request setDelegate:self];

    [request startAsynchronous];

}

我得到输出:

{"status":21002,"exception":"java.lang.NullPointerException"}

有人可以帮我收到正确的收据验证吗？

Answer 1

只为那些可能觉得有帮助的人.我注意到苹果已经在In App Purchasing Guide中更新了一些用于自动续订订阅购买的状态代码,但似乎也适用于此处.

• 21000 App Store无法读取您提供的JSON对象.
• 21002收货数据属性中的数据格式错误.
• 21003收据无法通过身份验证.
• 21004您提供的共享密码与您帐户的共享密钥不符.
• 21005收据服务器当前不可用.
• 21006此收据有效但订阅已过期.当此状态代码返回到您的服务器时,收据数据也会被解码并作为响应的一部分返回.
• 21007此收据是沙箱收据,但已发送到生产服务部门进行验证.
• 21008此收据是生产收据,但已发送到沙盒服务进行验证.

重要说明:此处的非零状态代码仅适用于恢复有关自动续订订阅的信息.在测试其他类型产品的响应时,请勿使用这些状态代码.(真？)

我希望这有助于作为参考.我用21007钉了.

经过多次尝试,我决定从服务器端进行收据验证.实际上这是推荐的方式.

这是我的代码,

-(void)recordTransaction:(SKPaymentTransaction *)transaction {   

NSString* receiptString = [[[NSString alloc] initWithData:transaction.transactionReceipt encoding:NSUTF8StringEncoding] autorelease];

// POST this string to your server

// I used ASIFormDataRequest 

}

// server side 

$url = 'https://sandbox.itunes.apple.com/verifyReceipt';

// encode the receipt data received from application

$purchase_encoded = base64_encode( $purchase_receipt );

//Create JSON

    $encodedData = json_encode( Array( 
        'receipt-data' => $purchase_encoded 
    ) );


// POST data

    //Open a Connection using POST method, as it is required to use POST method.
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_POST, true);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $encodedData);
    $encodedResponse = curl_exec($ch);
    curl_close($ch);


  //Decode response data using json_decode method to get an object.

      $response = json_decode( $encodedResponse );


// check response

if ($response->{'status'} != 0)

    // Invalid receipt

else

   // valid reciept
